Question

In a crystalline solid anion y are arranged in cubic close packing .cation x are equally distributed between octahedrl and tetrhedral voids.if all the octahedral voids are occupied yhe chemical fornulla of the solid is

Answer 1

Ccc=FCC means Y=4
A//q no. Of octahedral voids are full filled means 4 octahedral voids and 4 tetrahedral voids are present
Hence X= 8
Formula, Y4X8
